Patented March 16, 1909.

Application filed Apri17, 1908. Serial No. 425,612.

To all whom it may concern: I p

Be it known that we, HENRY H. Ons- TREIOHER, a subjectof the ,Em eror of Austria-Hungary, and ARTHUR J. LARLK, a citizen of the United States, and both residents of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Im roved' Cracker- Sandwich Machine, of wine the, following is a full, clear, and exact description. V

This invention relates to depositing the filler for making cracker or cake. sandwiches,

and it relates especially to such machines as are to operate upon a heavy, sticky filler substance, such as marshmallow-.- In the practical operation of such machines, on account of the sticky, pasty nature of the marshmallow, it is difficult to form the fillers or portions for the sandwiches ,from the mass of marshmallow in the feed reservoir.

The object of this invention is to provide improved means for forming the portions or fillers from the mass in the reservoir and ejecting the fillers upon the crackers.-

The invention consists in the construction Figure 1 is a side elevation of a machine constructed according to our invention; in this view a portion of an endless belt is broken away; Fig. 2 is a side elevation showing the opposite side of the machine from that which is shown in Fig; 1, portions ofthe endless belts being broken away; Fig. 3 is a vertical section through a art of the machine and viewing it from t e same side as Fig. 1, certain parts being broken away; and.

Fig. 4 is a plan of the machine, certain parts being broken away.

Referring more Iparticularly to the parts, and especially to igs. 1 to 3,1 represents the frame of the device, which comprises four standards 2 which support a box or reservoir 3 at their upper ends. This boxis formed with a bottom 4 having a plurality of openings 5 formed therein in two rows, as

indicated in Fig. 3, the openings in the two rows being in alinement transversely of the.

box as shown. Within the reservoir or box at these openings feed cylinders 6 are provided, which are of the same diameter asthe o enings. These cylinders are closed at t eir upper ends, and are provided with plungers 7 having enlarged, heads 8 which reci rocate within the cylinders, as will be reai ly understood. In order to reciprocate these rplungers simultaneously, their upper ends are all attached to a cross head 9 in the forrnof a horizontal plate, and this cross head is formed at its ends with guide pins 10 which extend intovthe slots formed in guides 11 which extend up from the sides of thebox as shown.

YYe provide means to be described hereinafter, for reciprocatingthe cross head 9. The sides of the cylinders 6 near the lower ends thereof, are providedwith feed openings '12 through which portions of the plastic confection 13 within the box may pass.

, Between the standards 2 an endless belt 14 is placed, the ends of the same passing around guide pulleys 15 and 16 supported on pedestals or bearing brackets 17 and 18 as shown, and beneath the belt 14.- a similar belt 19 "is rovided, which is driven in the direction of the arrow shown in Fig. 1. At

the rear side of the machine this belt19 passes around a guide pulley 20 mounted in suitable pedestals 21 as shown, and similar means for guiding the belt at its other end, is provided, though not shown. It should be stated, however, that the belt is extended to a distance so as to provide a large expanse or area ofbelt from which the finished sandwiches may be removed by attendants. The belt 19 may be considered as the delivery belt of the machine, for it delivers the finished product.

The. pedestals 17 have elevated extensions 22 which support. a horizontal driving shaft 23, the said driving shaft having a pulley 24 at one end thereof to receive a driving belt, as indicated in Fig. 4. On the shaft 23 a sprocket wheel 25 is provided, which is connected by a sprocket chain 26 with a similar sprocket wheel 27, the said sprocket wheel 27 being carried rigidly by a shaft 28 which is mounted between the extensions or arms 22 near the middle point thereof as shown. This shaft 28 is disposed between the runs of the belt 14 as indicated. The shaft 28 is further provided with sprocket wheels which are connected by sprocket chains 29 with sprocket wheels 29*; these, sprocket wheels .29 are rigid with idle gears 30* which mesh with, gear wheels 30 carried upon a transverseshaft 31 supported the pedestals 17 I i guide pulleys thereof; thereiarepmvidedi sprocket chains32, and on the shaft 31 there" are. provided mutilated. sprocket wheelscr;

segments 33, as indicated in Fig. 3, The sprocket wheels 33 have teeth 34 on a part of the circumference thereof, and. the upper run of the sprocket chains 32 lie near-the upper faces of the sprocket wheels, so that with each rotation of the shaft 31 thebe-l't: will be advanced. The advancing" movement' only takes place when the teeth. are in, contact with the chain so that bythi'smeans a step-by step or interrupted rnovement-isa produced. A similar arrangement is adopt ed for advancing the belt 14, for=which-pur pose the shaft 28- is provided with mutilated sprocket Wheels 35: having teeth 36 which may mesh with the sprocket chain 14*, as indicated. In this way a step-by-step advancing movement is: given to the belt. 1 4-. The shaft 23 isfurther provided with; a sprocket wheel 37 over which runs'asprocket chain 38; the other. end of this-chain runs around a sprocket wheel 39 rotatablymount-- ed on the end of the box or reservoir Rigid with this sprocket wheel 39' there is provided a crank 40, and this cra'nki-is-coirnected by means of a pitman or connecting:

rod 41 with the aforesaid cross head 9 From this arrangement, as the machinery is' driven, the cross head 9 is continuously reciprocated up and down.

The openings 5 are normally closed by means of a gate or sliding plate 42, which is provided with upwardly extending guide arms 43 at the ends thereof, which lie close" to the ends of the boX. These guide arms 43 are formed at their upper ends intohorizontal guides 44 which receive outwardly projecting pins 45 on the ends of the box. The guide arms 43' are connected to' a yoke 46, and this yoke has a bar 47 extending longitudinally of the box on the side thereof near the pedestals 17. Thisbar 4T is'further provided with a rigid arm- 48' which projects over toward the shaft 23, and this arm car'- ries a roller 49 which runs a cam slot 50in the face of the cam 51, which is rigidly attached to the shaft 23. This cam is formed with a circumferentially disposed art or inner are 52, and a circumferentia-ly dis.- posed part 52 or outer arc. These arcs are connected by inclined grooves which complete the cam.

The gate 42 has openings 53 which may aline with the openings 5 aforesaid. When the roller 49 is running in the inner-arc 52" of the cam, the gate is held closed, but when running in the outer arc the gate is open. The relation of the movement is such thatthe gate 42 is held closed while the plungers' 7 are moved upwardly. In this way a'parti'alz heil wen. nds-eithecyli ders vacuum is formed by the plunger heads 8 in Thisvacuum is broken when the lower ends of the headsfieheeome. raised above the lower edges of the openings 12. When this occurs, the 1 atmospheric; pressure forces portions of the confection 13 through the feed openings 12 intothe lower parts of the cylinders. The 'plungers then begin to eject the confection onto the crackers orca-kes which are arranged inrows on the belt: 14. These crackers or cakes are arranged in place by attendants standing atthe-right' end ofjthe machine as in'Eig; 1. The cakes or crackers having the confection deposited advance toward theleft; "At 'thispoint the attendant will stand,- who place the crackers from the belt-1=4 upfon'nthose lying on the belt 19 soas to form. a sandwich. It should be stated that at the right end of the machine, as viewed in Fig: 1', attendants stand to place the crackers upon the belt 19 in rows at marked-ii points on the belt, so that these crackers are delivered in rows at the same time as therows are delivered from the belt- 14. It: willjbeobserved that the lower edges ofthefeed openings=1 2 are horizontal, so that as the heads 8 move up, the vacuum in the feed cylindersis suddenly broken. The atmosphericpressure? therefore operates suddenly'to-forcea portion of'them-ass of'marshmallow into the lowerparts of. the cylinders. In addition tothe guides 44 we provide guide-bars 43 on the sides of the reservoir, on which the members-.43 slide as the gate: movesto and fro.

Having thus described our invention, we claim as new and desire to secure by Letters Patent,-

1". In a machine-of theclass described, in combination, a reservoir for apasty confec-- tion, a-fee'd cylinder having afeed 0 ening from said reservoir, a reciprocating p unger for producing a partial vacuum in said feed cylinder and adapted to uncover said opening, said feed opening being of great width at the point first uncovered by said plunger,

whereby atmos heric pressure is-suddenly ap lied to fee the confection into said cy inder.

2; In a machine of the class described, in combination, a reservoir adapted to receive a pasty confection, afeed cylinder mounted said reservoir-and having a feed opening leading from said reservoir, a plunger reciprocating in said cylinder adapted to uncover saidop'ening, a gaternormally closingthe lower end of said cylinder during the upward movement 'of'said plunger whereby a partial vacuumis produced within said cylinder, said feed: opening being of great width at theloweredge thereof whereby the partial vacuum formed withinisaid cylinder becomes suddenly broken" by the upward movement of said plunger.-

3. In a machine of the class described, in combination, a reservoir adapted to receive a pasty confection, a plurality of feed cylinders, a plurality of plungers moving in said cylinders, means for reciprocating said plungers, a gate normally closing the lower ends of said cylinders during the upward movement of said plungers, said feed cylinders having openings communicating with the opening of said reservoir disposed above the lower limit of movement of said plungers whereby a partial vacuum is produced within said cylinders during the first part of the upward movement thereof, said openings having their greatest width below whereby the upward movement of said plungers suddenly breaks said vacuum to feed the confection through said openings by suddenly applied atmospheric pressure, and means for opening said gate to discharge the confection.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
